The Canadair CL-44 was based on the Bristol Britannia but for some reason the FAA wouldn't certify it with the original Britannia cockpit windows. So Canadair, which was then owned by General Dynamics which also owned Convair, adapted the Convair 880/990 cockpit windows to fit the CL-44. The version of the CL-44 built for the Canadian Air Force (which didn't require FAA certification) retained the original Britannia cockpit windows..

Boeing 767. What can I say, it just looks cute and adorable from front on I remember overhearing someone commenting on how the 767 looks like a dolphin from that angle ... and I guess to an extent, it does!
